Murchison, Australia
Specific Gravity:
4.22 (Calculated)
Crystal System:
The name murchisite is for the town of Murchison, Australia near which the meteorite was found. The name “murchisonite,” was not used because it was used during the nineteenth century as a synonym for orthoclase.
Known as a synthetic compound.
